ABSTRACT

A fluorine-modified silicone derivative having an organopolysiloxane chain which is partly substituted by the siloxane chain of the following general formula (1), (2) or (3), ##STR1## where R 1 , R 2 , R 3 , R f , R f  &#39;, l, m, n and r are as described herein, a preparation process thereof, intermediates useful for the preparation thereof and cosmetic compositions containing this derivative.

TECHNICAL FIELD

The present invention relates to a fluorine-modified silicone derivative, a preparation process thereof, and cosmetic compositions containing such a silicone derivative, and more particularly to a novel fluorine-modified silicone derivative having excellent water and oil repellency, a preparation process thereof, and cosmetic compositions containing such a silicone derivative and having good lastingness of makeup and feeling upon use.

BACKGROUND ART

Various water-repellent cosmetic compositions have heretofore been used with a view toward protecting the skin from water and sweat and preventing makeup from getting out of shape by water or sweat. For example, skin care cosmetic compositions such as skin creams and skin lotions, and makeup cosmetic compositions comprise a silicone oil or silicone resin as a water-repellent component. However, these silicone oil and resin can exhibit some effect on water repellency, but has no satisfactory effect on oil repellency. Therefore, cosmetic compositions in which these components are incorporated have a problem that they can not last makeup longer due to the excretion of sebum.

Therefore, attempts to develop a compound having both water repellency and oil repellency have been made in various fields. For example, Japanese Patent Application Laid-Open No. 295912/1990 discloses that a cosmetic composition in which a specific fluorine-modified silicone compound is incorporated is excellent in water resistance and sebum resistance.

Water- and oil-repellent base substances used in cosmetic compositions are required to satisfy all such conditions that (a) they have sufficient water and oil repellency for sweat and sebum, (b) they are excellent in emulsion stability and (c) they are not sticky to the touch and good in feeling upon use.

However, the above-described fluorine-modified silicone compound does not fully satisfy these requirements, in particular, oil repellency.

Accordingly, there has been a demand for development of a compound which is excellent in water and oil repellency, and moreover can last makeup longer when incorporated in a cosmetic composition and gives a user of the cosmetic composition a good feeling upon use.

In view of the foregoing circumstances, the present inventors have carried out an extensive investigation. As a result, it has been found that a specific fluorine-modified silicone derivative, which will be described subsequently, has excellent water and oil repellency and exhibits good compatibility with cosmetic components, thus leading to completion of the present invention.

In the above reaction scheme, the compound represented by the general formula (16) can be obtained easily and cheaply by reacting a compound of the following general formula (17):

    Rf(CH.sub.2).sub.m OH                                      (17)

wherein Rf and m have the same meaning as defined above, with epichlorohydrin in the presence of an alkali metal hydroxide (Japanese Patent Application Laid-Open No. 193236/1989).

The reaction of the thus-obtained compound (8), (9) or (11) with the silicone derivative having polysiloxane units represented by the general formulae (7) and (4) is conducted in the presence of a catalyst. Examples of the catalyst used include catalysts generally used in hydrosilylation, for example, free-radical initiators; photoinitiators; complex compounds of metals such as ruthenium, rhodium, palladium, osmium, iridium and platinum; and those obtained by supporting these catalysts on silica gel or alumina. Of these, chloroplatinic acid, Speier reagent (a solution of chloroplatinic acid in isopropyl alcohol) and the like are particularly preferred. No particular limitation is imposed on the amount of the catalyst to be used so far as it is a sufficient amount to facilitate the reaction of the silicone derivative with the compound (8), (9) or (11). However, the amount is preferably within a range of 10⁻⁶ -10⁻¹ mol per mol of the compound (8), (9) or (11).

In this reaction, it is not essential to use a reaction solvent. However, the reaction may be conducted in a suitable solvent as needed.

However, for example, hydrocarbon solvents such as pentane, hexane and cyclohexane; benzolic solvents such as benzene, toluene and xylene; etheric solvents such as diethyl ether and diisopropyl ether; alcoholic solvents such as methanol, ethanol, isopropyl alcohol and butanol are particularly preferred.

The hydrosilylation is allowed to proceed at 0°-200° C. It is however preferable to conduct the reaction at 50°-150° C. in view of reaction rate and coloring of the reaction product. The reaction time is preferably within a range of from about 0.5 to about 24 hours.

Incidentally, in order to control various properties, such as viscosity, solubility and emulsion stability, of the fluorine-modified silicone derivative (A) obtained by the above reaction, it is only necessary to suitably change the combination of the kinds, amounts and the like of the silicone derivative having the polysiloxane units represented by the general formula (7) and (4) and the compound (8), (9) or (11).

The thus-obtained fluorine-modified silicone derivative (A) according to the present invention is excellent in water and oil repellency, and its properties such as viscosity may be controlled as necessary for the end application intended. Therefore, when it is used as an oily substance in a cosmetic composition, the cosmetic composition can be provided with excellent lastingness of makeup and feeling upon use imparted thereto. In this case, no particular limitation is imposed on the amount of the fluorine-modified silicone derivative (A) to be incorporated. However, it is preferable to incorporate it within a range of generally 0.001-90 wt. % (hereinafter indicated merely by "%"), preferably 0.1-70%.

In the cosmetic compositions according to the present invention, which contain the fluorine-modified silicone derivative (A), it is possible to additionally use oily substances employed routinely in cosmetic compositions. Examples of such oily substances include cyclic silicones such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane; nonvolatile silicones such as methylpolysiloxane, dimethylpolysiloxane and methylphenylpolysiloxane; animal and vegetable oils and fats such as squalane and palm oil; and others including hydrocarbons, higher fatty acid esters, liquid paraffin and liquid isoparaffin.

Further, in the cosmetic compositions according to the present invention, may be used insoluble powders routinely used in cosmetic compositions and insoluble powders treated with silicone or a fluorine compound. No particular limitation is imposed on the insoluble powders so far as they are substantially insoluble in water and oil like pigments and ultraviolet absorbents. Examples thereof include inorganic pigments such as titanium oxide, iron oxides, ultramarine blue, zinc white, magnesium oxide, zirconium oxide, mica, sericite, talc, silica, kaolin, chromium hydroxide and carbon black; organic powders such as nylon powder and powders of polymethyl methacrylate, styrene-divinylbenzene copolymers and polyethylene; organic coloring matter; finely particulate titanium oxide, zinc oxide and flaky zinc oxide as ultraviolet absorbents; and the like. In particular, it is preferable to use a fluorine compound-treated insoluble powder because makeup is prevented from getting out of shape due to the excretion of sebum.

Furthermore, in the cosmetic compositions according to the present invention, ingredients, which are mixed routinely in cosmetic compositions, for example, solid and semisolid oils such as vaseline, lanolin, ceresin, microcrystalline wax, carnauba wax, candelilla wax, higher fatty acids and higher alcohols; water-soluble and oil-soluble polymers; coloring materials such as organic dyes; surfactants such as anionic surfactants, cationic surfactants, nonionic surfactants, dimethylpolysiloxanepolyoxyalkylene copolymers and polyether-modified silicones; and others including water, antiseptics, antioxidants, coloring matter, thickeners, pH regulators, perfume bases, ultraviolet absorbents, moisturizers, blood circulation-facilitating agents, cold sensation-imparting agents, antiperspirants, disinfectants and skin activators may be incorporated suitably, as needed, so far as they do not impede the effects of the inventive silicone derivative.

In the cosmetic compositions according to the present invention, no particular limitation is also imposed on their forms and kinds. They can be formulated in accordance with the methods known per se in the art and are applied to, for example, oily cosmetics, emulsified cosmetics, water-based cosmetics, lip sticks, cheek rouges, foundations, skin cleaners, hair shampoos, hair tonics, hair styling preparations, hair grooming preparations, hair growth stimulants, etc.

While stirring the contents at 50° C., a solution of 139.0 g (177.3 mmol) of a compound (16a) [in the formula (16), Rf=Rf'=C₆ F₁₃, m=n=2] in tetrahydrofuran (180 ml) was added dropwise over 30 minutes. After a reaction was conducted for 5 hours at 50° C., the reaction mixture was allowed to cool. After cold water was added to the reaction mixture to take out an organic layer, an aqueous layer was extracted twice with chloroform, and the extract was united with the organic layer. The thus-collected organic layer was dried over anhydrous magnesium sulfate, and the solvent was distilled off, thereby obtaining a crude product. The thus-obtained crude product was distilled under reduced pressure, thereby obtaining the intended fluorine-containing compound (9a) (115.7 g, 79.0%). Boiling point: 130°-132° C./1.8×10⁻² mmHg.

Preparation Example 1 Preparation of Fluorine Compound-Treated Sericite

A one-liter round bottom flask (or kneader) was charged with 100 g of sericite, to which 500 ml of deionized water was added. Thereafter, 33 g of an about 17.5% aqueous solution of a dioxyethylamine salt of a perfluoroalkylphosphoric ester [(C_(m) F_(2m+1) C₂ H₄ O)_(y) PO(ONH₂ (CH₂ CH₂ OH)₂)_(3-y) ] [m=6-18 (average chain length: 9), 1<y<2] was added to the resulting mixture to stir them at 40° C. Then, 40 ml of 1N hydrochloric acid was added to lower the pH of the aqueous solution to 3 or lower, thereby depositing perfluoroalkylphosphoric acid on the surface of the powder. Thereafter, the powder was collected by filtration, washed with water and dried to obtain 105 g of the intended fluorine compound-treated sericite.

As apparent from Table 5, the liquid foundations according to the present invention were superior in lastingness of makeup and feeling upon use to those containing silicone heretofore in use.

Example 25 Powder Foundation

A powder foundation having the following composition was prepared in accordance with a preparation process described below.

Preparation Process

Pigments are mixed and ground in a mill. The thus-ground pigment mixture is transferred to a high-speed blender, to which an intimate mixture obtained by mixing a binder and the like under heat is added, followed by intimate mixing. The thus-obtained intimate mixture is treated in a mill, sifted to make its particle size even and then left over for several days. Thereafter, the mixture is compression-molded in a container such as a metal pan to obtain the powder foundation.

Pigments were mixed and ground in a mill. The thus-ground pigment mixture was transferred to a high-speed blender, to which an intimate mixture obtained by mixing a binder and the like under heat was added, followed by intimate mixing. The thus-obtained intimate mixture was treated in a mill, sifted to make its particle size even and then left over for several days. Thereafter, the mixture was compression-molded in a container such as a metal pan to obtain a powder foundation.

Example 40 Powder Foundation

A powder foundation having the following composition was prepared in accordance with a preparation process described below.

Preparation Process

Pigments are mixed and ground in a mill. The thus-ground pigment mixture is transferred to a high-speed blender, to which an intimate mixture obtained by mixing a binder and the like under heat is added, followed by intimate mixing. The thus-obtained intimate mixture is treated in a mill, sifted to make its particle size even and then left over for several days. Thereafter, the mixture is compression-molded in a container such as a metal pan to obtain the powder foundation.
